| Abstract(in English) | This paper proposes a novel approach for learning a decision tree from a data set with time-series attributes. A time-series attribute takes, as its value, a sequence of values each of which is associated with a time stamp, and can be considered as important since it frequently appears in real-world applications. Our time-series tree has a time sequence in its internal node, and splits examples based on similarities between a pair of time sequences. We first define our standard example split test based on dynamic time warping, then propose a decision tree induction procedure for the split test. Experimental results confirm that our induction method, unlike other methods, constructs comprehensive and accurate decision trees. Moreover, a medical application shows that our time-series tree is promising in knowledge discovery. |
